Thickness Guide
At 3 mil, these bags fall into the heavy-duty category. For comparison: 1.5 mil bags suit light dust protection, 2 mil handles general-purpose applications, while 3 mil provides the durability needed for sharp edges, repeated handling, and long-term archival storage. Choose 3 mil when contents have corners, frames, or require extra protection during transit.
